Procurement Notes

Verify the specific suffix 'CPD' corresponds to the PDIP-8 package and commercial temperature grade when sourcing. Confirm RoHS compliance status as indicated in official documentation. Ensure the supplier provides valid traceability for this discontinued or limited-stock component. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit units. Validate that the device meets the required electrical tolerances for your specific application design.

Selection Notes

Select this component when low cost and moderate precision are prioritized over ultra-low noise or high speed. The CMOS architecture offers high input impedance suitable for buffering high-impedance sources. Consider the limited bandwidth and slew rate for applications involving slow-varying signals. Verify that the 8-pin DIP package fits the available PCB footprint and assembly constraints.
